It was no trouble at all.

Unfortunately, I don't know of a quicker way to do the second one at the moment. Sorry about that...
I'd have to do some experimenting, maybe, unless someone knows of a faster way.

As for the [unparseable or potentially dangerous latex formula], if you have - say - [unparseable or potentially dangerous latex formula] fractions like that to add (like in the denominator 6*7, 7*8, 8*9...) then you just substitute that [unparseable or potentially dangerous latex formula] with the [unparseable or potentially dangerous latex formula]...

Thanks! Looks painful though, but I'll manage.

At one point I did know how, but I forgot over the summer.

Another way of LCMing is to use prime factorization...

i mean this is about the same way but instead of taking common factors, you are just breaking it down to till the end - to prime factors - and then finding a solution to the problem...

Yeah, that's what I usually do, but I was hoping to see if there was a slightly quicker way. The numbers aren't usually as perfect as the ones you've given me, I think.

It's okay. Can't seem to think of any off the top of my head. I guess I'll just slow down on those a bit. "Analyze" before answering. I don't care much about speed right now, seeing as I'm missing easy problems left and right. Thanks, though.

I always see these...
